Problem with Table.getformatdata

Today, I tried to copy the format data of the 3D Animations table into another table. It does copy the format data. However, it only copies the data of the outer table. That is, the table with 2 columns with type String(name of the AniPath) And table(inside which are the co-ordinates of the animation path to be set). It does not copy the format data of the table inside for which the type should be real. Is it just me, am I doing something wrong or is this a bug?
